NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 692,205, dated January 28, 1902.

Application filed May 23, 1901- Serial No. 61,609. (No model.)

To a whom it may concern.-

Be it known that I, ARTHUR CHARLES CAV- ENDISH LIARDET, gentleman, a subject of the King of Great Britain, residing at 16 Broad street, New York, N. Y., have invented certain new and useful Improvements in Non- Refillable Bottles, of which the following is a specification.

This invention relates to non-refillable bottles, and particularly to those of the kind in which there is employed a hollow floatvalve normally maintained on a seat at the upper end of a tube by a hollow weight suspended from said float'valve by a flexible connection, the said float-valve being protected from improper operation by a plug or bafiie arranged above it in the neck of the bottle. Apparatus of this kind was set forth in the specification of my prior patent, No. 665,023, dated January 1, 1901.

The invention further aims to construct a non-refillable bottle which shall be simple in its construction, strong, durable, efiicient in its use, and comparatively inexpensive to set up; and tothis end it consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In order that my said invention may be clearly understood and readily carried into effect, I will describe the same more fully with reference to the accompanying drawings, in which Figures 1 and 2 are vertical sections of a bottle constructed in accordancewith myinvention and provided with my improved apparatus, Fig. 1 representing the bottle in its upright position and Fig. 2 representing it in its tilted position for pouring out the liquid contents. Fig. 3 is an elevation, and Fig. 4 a vertical section, of the plug or baffle detached from the bottle. Fig. 5 is a vertical section of a modified form of the bottle-neck, and Fig. 6 is a transverse section of the same on the line A A of Fig. 6.

a is the hollow float-valve, and b the weight suspended therefrom by the flexible connection 0.

(Z is the tube, formed with a seat at the upper end for the float-valve, and e is the plug or baffle. The said hollow float-valve presents a conical or pear shaped appearance and is partly filled with the liquid, shot, or other mobile substance a as aforesaid, so that when the bottle is tilted into a position for pouring out the liquid contents therefrom the change of position of the liquid or shot within the valve will act to upset the latter, and thereby facilitate the readiness with which it will leave its seat at the upper end of the tube d, and thus avoid delay in the passage of the liquid from the bottle. .For the purpose of enabling the aforesaid liquid or shot to be placed within the hollow valve the latter may be formed with an opening at its upper end closed by a cork or other stopper a. It will be obvious that the quantity of liquid or shot placed in the said hollow valve should be such that the latter will not be prevented from freely floating in alcohol. The portion of the said valve near its bottom is preferably ground around the periphery to form a seating a for cooperating with the seat at the mouth of the tube d. The exterior surface of the upper part of the said valve may be made plain or it may be formed with longitudinal ridges or recesses. The bottom of the said valve is preferablyformed with a cavity or depression a within which is located a hook or eye a formed integrally with the said bottom of the valve for receiving the upper-end of the cordc or other fiexible connection between the valve and the weight b, the said cord being attached at b to the bottom of the weight. Instead of the hook or eye I may of course employ any other suitable contrivance for the said flexible connection to be attached to. The aforesaid depression or cavity offers a satisfactorysurface for contact with the liquid when the bottle is tilted, so as to assist in unseating the valve should it for any reason stick. This depression or cavity further insures the correct seating of the valve, as by it a portion of the curved bottom of the valve is removed. Consequently thereis less danger of the valve catching on the upper edge of the tube (1 without seating properly. In other words, if the valve seats at all it must seat properly.

I find it very advantageous to form the ICO float-valve to its seat.

aforesaid weight b of the shape represented in the drawingsthat is to say, with the portion 17 between its ends inclined or conical, while the said ends are cylindrical. The said inclined portion 19 may also be formed on its outer surface with a series of longitudinal grooves or recesses for the liquid to freely pass by the said Weight when the latter enters the tube (1 as the bottle is tilted to pour out the contents. The aforesaid inclined portion 19 of the weight when the bottle is tilted seats itself on the lower end of the said tube, and when the bottle is moved from its tilted position toward the horizontal this inclined portion enables the float-valve to immediately return to its seat. This is due to the fact that as the bottle approaches the horizontal position the said inclined portion of the weight (which at such time finds a temporary resting-place or fulcrum upon the edge of the tube d) will at once slide over the said edge, and by thus overbalancing itself will promptly fall out of said tube as far as it can, thereby pulling the float-valve back to its seat. The dimensions and heaviness of the bottom portion of the weight-that is to say, the cylindrical part belowgthe inclined portion Zfi-will be determined by the relative size of the other parts of the apparatus. Obviously the heavier the bottom of the Weight the quicker will it operate in seating the float-valve and the slower will it be in permitting the unseating of said valve.

The aforesaid tube d is provided at its upper end with an annular head 01, the inner circumference cl of which is inclined toward the valve-seat of such tube. This inclined portion is, however, of slightly greater circumference than the seating a of the floatvalve, its purpose being to assist or guide the The said tube is provided with a collar or ring d of cork or similar resilient material,which abuts against the under side of the said annular head. When the said tube and its cork collar are being placed in position, the outer edge of the said collar or a portion thereof engages with an annular groove fformed for its reception in the neck of the bottle.

61 d are spiral slots or openings in the wall of the tube for the liquid to gain ready access to the tube when the bottle is tilted and the weight engaging with the lower end of said tube.

The plug or baffle e, which is located in the neck of the bottle just above the float-Valve, is formed of a hollow cylinder of glass or other appropriate material,with its upper end closed and of more or less hemispherical shape. The lower end of the said baffle is diminished in diameter to form a shoulder e, which acts in conjunction with a shoulder f on the interior of the bottle-neck to prevent the baffle from being pushed too far into the bottle.

This shoulder f also serves to prevent a wire or similar instrument from reaching the floatvalve, if such wire should by any possibility have been passed between the baffle and the bottle-neck. The said baffle is formed with several lateral passages e 6 which are surrounded with inwardly-projecting walls a which taper toward their inner end. The lower parts of said walls are provided with serrations or ribs c, which assist in forming an effectual guard against the possibility of an instrument being passed through the openings c with the object of holding the floatvalve raised from its seat. I also form the eX- terior of the baffle with an annular groove a which provides a gap between the vertical corrugated portions e and'e so that the corrugations in one portion may break joint with the corrugations in the other portion, and thereby offer effectualimpediments to the passage of a wire or the like between the baflfle and the neck of the bottle. These corrugations and the lateral passages 6 provide for an efficient outflow of liquid and inflow of air from and to the bottle when the contents are being poured out. Moreover, the lower end of the baffle, into which the head of the valve projects, serves as a stop to prevent the said valve from'becoming too much displaced from its seat when the contents are being poured from the bottle. In order to retain the baffle firmly in place within the bottle-neck, I provide said baffie with segmental grooves or sockets 6 preferably' three in number, to receive loose non-spherical bodies e ,which when the baffle is in place engage with a continuous annular groove f in the bottle-neck. In place of a continuous annular groove I may employ an interrupted groove ora series of interrupted grooves, as represented in Figs. 5 and 6, so that plain portions f exist between the ends of the grooves-and prevent the cork collar d from engaging with said grooves, thereby facilitating the easy passage of the said cork collar through the bottle-neck. In Fig. 5 I have shown three sets of the interrupted grooves located one above the other, so that the position in which the said baffle is placed in the neck of the bottle can be chosen accordingly. Obviously, however, the number of the sets can be varied in accordance with requirements. \Vhen there is more than one set of the grooves employed, the plain portions f will present smooth surfaces to the loose locking members (2 and prevent them from leaving their sockets while the baffle is being inserted into place. By giving an angular movement to the baffle when it has been pushed into the neck to the required extent the said sockets can be brought opposite the grooves in the bottle-neck and the loose locking members he thus permitted to assume their locking position. By mak ing the sockets e elongated in a lateral direction, as represented in Fig. 3, I can provide for the baffle being adjusted angularly even after the locking members are in their engaging position, if such adjustment should be necessary to facilitate the proper seating of the locking members in their gIOOXGS.

ICC

I am aware that attempts have previously been made to secure a battle in the neck of a bottle by means of locking members engaging with recesses in the bottleneck and the baffle; but so far as I am aware it has not before been proposed to use non-spherical locking members engaging with elongated recesses or grooves in the bottleneck and the baffle.

What I claim, and desire to secure by Letters Patent of the United States, is

1. In a non-refillable bottle, the combination of a hollow float-valve having a hemispherical self-seating lower part and a pointed upper part terminating in a mouth for enabling a liquid to be placed within said hollow valve, of a stopper for closing said mouth, of a tube entirely open at both ends and formed at its upper end with a flanged portion having a cup-shaped head leading to a seat for said valve, of a cork collar surrounding said tube at the part immediately below said flanged portion and adapted to engage with a groove in the bottle-neck, and of a hollow weight formed with cylindrical ends and a conical intermediate portion formed with grooves in its exterior, the lower end of the said weight being of larger diameter and greater weight than the upper end and said weight being suspended from the lower end of said valve by a flexible connection extending from the lower end of the weight to the lower end of the valve substantially as and for the purpose specified.

2. In a non-refillable bottle, the combination of a hollow float-valve having a hemispherical self-seating lower part flattened or dished at the bottom and a pointed upper part terminating in a mouth for enabling liquid to be placed within said hollow valve, of a stopper for closing said mouth, of a tube entirely open at both ends with spiral slots in its sides and formed at its upper end with a flanged portion having a cup-shaped head leading to a seat forsaid valve, of a cork collar surrounding said tube at the part immediately below said flanged portion and adapted to engage with a groove in the bottle-neck, and of a hollow weight formed with cylindrical ends and a conical intermediate portion having grooves in its exterior, the lower end being of larger diameter and greater weight than the upper end, and said weight being suspended from the lower end of said valve by a flexible connection extending from the lower end of the weight to the lower endof the valve substantially as and for the purpose specified.

3. In a non-refillable bottle, the combination with the float-valve, the open-ended tube and the weight, of a baffle comprising a hollow cylindrical plug closed at its upper end and formed with lateral openings through its walls, and with sets of vertical corrugations on its exteriorseparated by an annular groove, the corrugations of one set breaking joint with those of another set, of beaded internal flanges surrounding the aforesaid lateral openings, of loose non-spherical locking members engaging with sockets in the plug and with grooves in the bottle-neck, of a shoulder at the lower open end of the plug formed by diminishing the diameter of said open end, and of a shoulder on the bottle-neck against which the said shoulder on the plug bears when the latter is in place substantially as and for the purpose specified.

4. In a non-refillable bottle the combination with the float-valve, the open-ended tube and the weight, of a battle comprising a hollow cylindrical plug closed at its upper end and formed with lateral openings through its wall and with sets of vertical corrugations on its exterior separated by an annular groove, the corrugations of one set breaking joint with those of another set, of beaded internal flanges surrounding the aforesaid lateral openings, of loose non-spherical locking members engaging with elongated sockets in the plug and with one or other of a series of interrupted grooves in the bottle-neck, of a shoulder at the lower open end of the plug formed by diminishing the diameter of said open end, and of a shoulder on the bottle-neck against which the said shoulder on the plug bears when the latter is in place, substantially as and for the purpose specified.
